The new findings on the Late Devonian volcanism in the Eastern Taurides (Develi, Kayseri): Preliminary data

Öz

The Tauride-Anatolide Platfom includes of widespread Paleozoic (Cambrian to Permian) units, which rarely consist magmatic rocks that were identified in two areas: Eastern Taurides (SW of Tufanbeyli and Yahyalı) and Central Taurides (Northern Konya). There are problematic views related to the magmatic evolution of these rocks. The available geochemical database is mostly concentrated on the magmatics from the Central Taurides (Konya Region). 

In this study, the mafic volcanic rocks were recently found in the Eastern Taurides (Develi-Kayseri). These mafic volcanics are intercalated with the Late Devonian limestones and covered by the Early Carboniferous sandstones. The geochemical charateristics of the volcanic rocks exhibit back arc basin (BAB) features with slightly negative Nb anomalies, normal-MORB (NMORB)-like high field strength element (HFSE) patterns and flat REE profile. 

The newly found basic volcanic rocks in the Eastern Taurides geochemically resemble the meta-diabase dykes in the Konya and Yahyalı regions, which were assigned to a subduction related event. The new data reported in this study will benefit to better understand the mid-Paleozoic evolution of the Taurides.

Doğu Torid’lerdeki (Develi-Kayseri) Geç Devoniyen volkanizması üzerine yeni bulgular: İlk veriler

Öz

Torid-Anatolid Platformu Doğu Torid’ler (Tufanbeyli ve Yahyalı’nın GB’sı) ve Orta Torid’ler (Kuzey Konya) bölgelerinde nadiren tanımlanmış olan magmatik kayaçları barındıran yaygın Paleozoyik birimleri içermektedir. Bu kayaçların magmatik evrimi ile alakalı tartışmalı görüşler bulunmaktadır. Ulaşılabilir jeokimyasal veriler Orta Torid’lerdeki (Konya Bölgesi) magmatik kayaçlar üzerine yoğunlaşmıştır. 

Bu çalışmada, Doğu Torid’lerde (Develi-Kayseri) mafik volkanik kayaçlar bulunmuştur. Bu mafik kayaçlar Geç Devoniyen yaşlı kireçtaşları ile ardalanmış ve Erken Karbonifer yaşlı kumtaşları tarafundan örtülmüştür. Volkanik kayaçların jeokimyasal karakteristikleri hafif negative Nb anomalileri, normal-MORB (N-MORB) benzeri yüksek alan dayanım element paternleri (HFSE) ve düz NTE profili ile yay-ardı havza özellikleri sunmaktadır.

Doğu Torid’lerde yeni bulunan mafik volkanik kayaçlar jeokimyasal olarak dalma-batma olayları ile ilişkilendirilmiş olan Konya ve Yahyalı bölgelerindeki metadiyabaz dayklarına benzemektedir. Bu çalışmada sunulan yeni veriler Torid’lerin Orta Paleozoyik evrimini daha iyi anlamaya fayda sağlayacaktır.
